Succubus (1967)

This international cult classic stars Janine Reynaud as Lorna, a nightclub performer whose act involves simulated murder, sex, and torture. Her husband (Jack Taylor) owns the club, and is worried about her. Her fantasies are becoming indistinguishable from reality, and maybe she is killing for real. A mysterious stranger (producer Adrian Hoven) follows her around, claiming to be a demon lover from the past. To try and describe any more would be futile. Suffice it to say, this is one of those 1960s art movies where a dwarf in a tuxedo solemnly puts LSD on everyone's tongue at a swinging party. Composer Jerry Van Rooyen keeps things jumping with an incredible score of strings and surreal jazz. It was a huge hit for director Jess Franco, who immediately followed it with TWO UNDERCOVER ANGELS and KISS ME MONSTER (both also starring Reynaud). This film has more nudity, sadomasochism, lesbianism, word-association, mannequins, murder, and general decadence than any sane person can soak up in one viewing; hence it needs to be seen twice.
